5.2.4.2 Debug Out using Renesas RA4M2 J-Link OB
The AIK-RA4E1 Debug Interface can be configured to use the Renesas RA4M2 to debug a RA4E1 device
on an external board.
A yellow indicator LED4 provides a visual status of the state of the debug interface. When AIK-RA4E1 is
powered on, and LED4 is blinking, this indicates that the Renesas RA4M2 debugger is not connected to a
programming host. When LED4 is on solid, this indicates that the Renesas RA4M2 is connected to a
programming interface.
